Twenty gallons of a salt solution consists of 40 % salt. It is the result of mixing a 55 % solution with a 25 % solution. How many gallons of each of the solutions was used? Let x = the number of gallons of the 55 % solution and y = the number of gallons of the 25 % solution. The x+y= 20 corresponding modeling system is {0.55x +0.25y = 0.4(20) .
